The Taxation of Colonies Act 1778 was an Act of the Parliament of Great Britain under the order King George III that declared Parliament would not impose any duty, tax, or assessment for the raising of revenue in any of the colonies of British America or the British West Indies. The Act, passed during the American Revolutionary War, was an attempt by Parliament to end the war by conceding one of the early points of dispute. The Act was eventually repealed by the Statute Law (Repeals) Act 1973 as obsolete.
